Convert JSON String to Dictionary in Android

Question

I have the following json formatted string that is returned from the web service:

{"Success":false,"Message":"This version is not supported"}

I am using the following code to invoke the web service:

AsyncHttpClient client = new AsyncHttpClient();

client.get("http://mywebsite/check/getcompatibilityinfo", new AsyncHttpResponseHandler() {
    @Override
    public void onSuccess(String response) {
        System.out.println(response);
    }
});

The response contains the json string now I need to access the Success and the Message property. Is there any simple way to do it without using complicated third party libraries?

Answer 1

The JSONObject class is already available in your Android codebase (no 3rd party dependencies). Since your example uses normal (simple) JSON, you can use:

try {
    JSONObject responseJSON = new JSONObject(response);
} catch (JSONException e) {
    e.printStackTrace();
}

boolean success = responseJSON.getBoolean("Success");
String message = responseJSON.getString("Message");
